Is the air quality in your house causing problems, but you don't have the space for a bulky air purifier? BlueAir has stepped up with the DustMagnet 5440i, now $80 off down to $239.99 at Amazon.

BlueAir is one of the biggest names in air purifiers and we've been impressed with their products so far. We chose the BlueAir Pure Max 411i as our best budget air purifier, and the DustMagnet 5440i is just as impressive.

The DustMagnet 5440i air purifier is on sale right now at Amazon for $239.99.

Its HEPASilent dual filtration means that, despite its compact size, it can clean a 357sqft room in around 12 minutes, or up to 1,700 sqft in 60 min. It's a great little purifier at full price, but at $80 off it's a must have for anyone looking to breathe a little easier.

The BlueAir DustMagnet 5440i is equally at home sitting on a table or tucked in to a corner and, thanks to its size and its quietness, you'll barely notice it's there.

With its HEPASilent system, it pulls dust out of the air before it's had a chance to settle. In their review of the BlueAir Dustmagnet 5440i, our sister site TechRadar reported: "...a marked improvement in overall air quality, including fewer lingering odors or smoke after cooking."

✅ Buy it if: You're after a compact but powerful air purifier that will handle mid to large rooms without dominating them.

❌ Don't buy it if: You want an expansive LCD display, or to cover very large 2000 sqft + rooms. Consider the BlueAir Blue Protect 7470i, which is 25% off on Amazon.
